Abstract

A carburetor assembly includes a carburetor, a fuel supply valve, a valve member and a normally open switch. The fuel supply valve is coupled to the carburetor housing and is fluidly connected to the carburetor. The fuel supply valve includes a lever pivotable between first and second positions. The valve member is configured to move in response to the lever such that fuel is allowed to flow to the carburetor when the lever is in the first position and fuel is not allowed to flow to the carburetor when the lever is in the second position. The normally open switch is adjacent the fuel supply valve and includes a switch actuator. The lever is configured to engage and release the switch actuator to move the switch actuator between a non-actuated position and an actuated position respectively when the lever moves between the first and second positions.
